5. The Global Oceanographic Data Archaeology and Rescue (GODAR) Project Established in 1993 by the Intergovernmental Oceanographic Commission. "Data Archaeology": the process of seeking out, restoring, evaluating, correcting, and interpreting historical data sets; "Data Rescue": the effort to save data at risk of being lost to the science community by digitizing manuscript data and copying data on older, failing electronic media, and then archiving these data into an internationally available electronic database.

7. Regional GODAR Project meetings • Six regional GODAR Project workshops were held worldwide that • encompassed all countries that make oceanographic measurements. • Attendance of these meetings in total was approximately 150 oceanographic • data managers and scientists. • GODAR I Obninsk, Russia May, 1993 • GODAR II Tianjin, China March, 1994 • c) GODAR III Goa, India December, 1995 • GODAR IV Valletta, Malta April, 1995 • GODAR V Cartagena, Colombia April, 1996 • GODAR VI Accra, Ghana March, 1997. • Each meeting produced a Workshop Report that included listings of data in • Manuscript and electronic form in each participating country.

8. International GODAR Review Meeting July 1999, Silver Spring, Maryland • Meeting conclusions: • GODAR Project has been successful, • variables to be included under the GODAR Project should be expanded to include sea level, • 3) GODAR-WESTPAC project be initiated.

9. INTERNATIONAL PROGRAM SUPPORT FOR DATA ARCHAEOLOGY AND RESCUE ACTIVITIES Support for data archaeology and rescue activities in oceanography and meteorology, and specifically for the GODAR Project has come from many sources, e.g., World Climate Research program's CLIVAR program (WCRP, 1995; 1999) and the IPCC Assessment (1996).

10. REASONS FOR BUILDING GLOBAL, HISTORICAL IN SITU OCEANOGRAPHIC DATA BASES • The international scientific community advises national and international bodies on such issues as climate change. • Historical data are required to support such studies. • The international scientific community must have access to the most complete oceanographic data bases possible. • These data bases must be accessible in electronic form and available internationally without restriction. • b) Ocean measurement programs are expensive. Scientists planning such programs should have access to all available data in order to make the most efficient use of scarce scientific resources such as ships. • c) Pollutants flow across boundaries. The international community should have access to all historical data for pollution transport studies. This is particularly important for studies of the coastal environment. Natural variability versus anthropogenically induced changes. • d) To develop and improve long-range weather forecasts. Statistical forecasting and hindcasting studies require historical ocean data.

11. Specific uses for ocean profile-plankton data and products a) Planning observational programs. b) Diagnostic studies describing role of the ocean as part of the earth's climate system. c) Boundary and Initial conditions for numerical models. d) Verification for ocean and atmosphere simulations. e) "Sea truth" for satellite ocean altimetry measurements". f) Initial state for acoustic tomography inversions. g) Paleontological reference fields (e.g. CLIMAP).

12. FINANCIAL SUPPORT FOR THE GODAR PROJECT The IOC has provided important support in the form of staff time and resources. The NOAA Climate and Global Change Program and the NOAA ESDIM Program have provided crucial support for U.S. participation, for meeting support, visits by scientific and data management personnel, and for digitization of many data sets for the world ocean. The European Community has provided support for the MEDAR/MEDATLAS project and for GODAR meetings. Individual countries and international institutions (e.g. ICES) have provided support as Japan is doing with its leadership of the GODAR-WESTPAC Project.

13. THE WORLD OCEAN DATABASE PROJECT • “World Ocean Database Project” was proposed by S. Levitus at the IODE XVI • meeting held in Athens, Greece during December, 2001. • The purpose of this project is to: • a) Encourage a more timely exchange of modern oceanographic data; • Encourage the development of regional quality control procedures for oceanographic data; • c) Encourage the development of regional oceanographic atlases. • Planning for a meeting on “Quality Control of Oceanographic Profile-Plankton • Data” will start soon. Meeting to be held within one year.

17. Recent scientific Results Made Possible through GODAR and WOD activities GODAR and WOD Projects added 2 million temperature profiles to internationally available databases such as WOD98. This allowed construction of yearly upper-ocean temperature anomaly fields. These anomaly fields are now being used to verify Ocean General Circulation Models driven by surface forcing fields, Zhang et al. (2001) Lysne and Deser (2002).

The contour interval is 0.4 K2 at 200m and 0.1 K2 at 400 m. Shading denotes values > 0.1 K2 at 200m and > 0.05 K2 at 400m. Dashed rectangles at 200m show the regions used to define the NW and SW Tropic Indices. Dashed rectangles at 400m denote the regions used to define the North Pacific Index.
